I have a PC running windows XP that has 4 x 1GB memory chips but when you run System from the control panel it states that I only have 3GB or ram. If you go into the bios it states all 4 slots are occupied.
What are my options is it that one of the chips is defective or is it a quirk of windows. Are their any free apps that I can run in windows to check the memory.
It is a CAD PC that really needs more memory but right now I am to busy to change over to a new PC as it would mean upgrading from XP and theirfore lots of other software might not work which is a chance I can't afford to take right now.
